Abstract (en)
Provided is a multilayer container having a polyester layer containing a polyester resin (X), and a polyamide layer containing a polyamide resin (Y) and a yellowing inhibitor (A). The content of the polyamide resin (Y) is from 0.05 to 7.0 mass% relative to the total amount of all polyamide layers and all polyester layers. The yellowing inhibitor (A) is a dye. The content of the yellowing inhibitor (A) is from 400 to 800 ppm relative to the polyamide layer. An L* value of the multilayer container is 87.5 or greater.
